概括
中脑膜动脉栓塞 (MMAE) 与手术相结合,在90天和180天显著降低了慢性下皮质血瘤 (cSDH) 的体积. 这种定量成像分析支持MMAE作为cSDH分辨率的有效辅助治疗.
科学领域:
- 神经外科 神经外科
- 干预性放射学 干预性放射学
- 医疗成像医学成像
背景情况:
- 慢性亚皮血瘤 (cSDHs) 在手术疏散后复发率很高.
- EMBOLISE试验显示,与单独手术相比,中脑膜动脉栓塞 (MMAE) 加上手术减少了重新手术的发生率.
- 需要定量成像指标来评估超出临床终点的cSDH分辨率.
研究的目的:
- 为了评估从EMBOLISE试验中预先指定的成像终点.
- 用定量成像分析来评估长期cSDH分辨率.
- 为了比较血瘤体积,厚度和MMAE加手术和单独手术之间的中线变化.
主要方法:
- 一个多中心,随机,干预性试验 (EMBOLISE) 涉及352名患者.
- 评估CT和MRI成像终点从手术后24小时到180天.
- 混合效应建模用于血液瘤指标的混调整分析.
主要成果:
- 接受MMAE加手术治疗的患者在90天 (20.6毫升 vs 28.9毫升) 和180天 (19.4毫升 vs 31.5毫升) 的时间里,cSDH体积显著降低.
- 经混调整后的分析显示,在MMAE组中,在90天后,体积减少率大约为25%,绝对体积降低了30%左右.
- 两组之间预先指定的二次成像终点没有发现显著差异.
结论:
- 在手术后90天和180天,辅助MMAE导致绝对血瘤体积显著降低.
- 定量成像分析表明,在MMAE时,cSDH体积的减少更大.
- 虽然预先指定的终点没有差异,但MMAE显示了改善cSDH分辨率的希望.

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Cranial and Spinal Meninges
3.9K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Pulmonary Embolism I: Introduction
667
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Clinical Trials: Overview
4.9K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Trial and Error and Algorithm
401
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...

Clinical Trials
10.3K
Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
